Starbucks Offering Discount to Foursquare Mayors

Through June 28, Starbucks is offering select users of the Foursquare social networking service a $1 discount on Frappuccino beverages. Users must be the Foursquare "mayor" of the Starbucks location, and the offer can only be redeemed once. Though other venues have offered discounts to Foursquare users in the past, the Starbucks offer is the largest deal to encourage use of the location-based social site, which offers users points and "badges" for reporting their presence at various locations and events. The deal also may signify an edge for Foursquare over competitor sites like Gowalla, MyTown and Booyah, which all offer a similar style of location-based networking. Foursquare currently offers a dedicated app for the iPhone, Android and BlackBerry platforms, as well as a mobile site for other users.
